As the agricultural sector consumes about 85% of Egypt's water resources, therefore new irrigation application methods must be searched to rationalize water use by increasing the irrigation efficiency. Field experiment was conducted to compare two water application methods to calculate the requirements of water for squash (Cucurbita pepo, L. var. Hybrid Revera) during the summer of season 2019. Two methods of irrigation water application were used and adapted to conditions of drip irrigation system: (i) method A using estimation of the reference evapotranspiration by using method of weather factors-dependent Penman-Monteith. (ii) method B is the water depletion from the soil, which depends on the water properties of soil. Crop water needs, yield, water use efficiency and the irrigation water amount lost by deep percolation were determined. The results showed that the irrigation method which dependent on the soil water properties has positive effects on the squash production compared to method A. Moreover, the highest value of water use efficiency was obtained by method B which was 5.31 kg m-3, while its value for method A was 4.33 kg m-3. Also, the highest yield was obtained by method B which was 15970.10 kg ha-1, while the productivity under method A was 15492.69 kg ha-1. In addition, the highest values of lost water through deep percolation (14.82 %) were detected with method A. Generally, method of irrigation soil-based was more accurate in calculating the amount of irrigation water added and had clearly positive effects on growth, yield and water use efficiency of squash compared to a climate-dependent irrigation method.}, keywords = {Reference evapotranspiration - Soil water properties - Water depletion,Squash crop}, url = {https://ejss.journals.ekb.eg/article_145188.html}, eprint = {https://ejss.journals.ekb.eg/article_145188_ae905644b3401cbc73b646c98124a8a0.pdf} } @article { author = {ELZEMRANY, Hamdy and Faiyad, Riham}, title = {Maximizing Use Efficiency of Mineral Fertilizers Using K Fulvate and Azotobacter chroococcum DSM 2286 and Their Effect on Wheat Production and Nutrients Uptake.}, journal = {Egyptian Journal of Soil Science}, volume = {61}, number = {1}, pages = {13-25}, year = {2021}, publisher = {The National Information and Documentation Centre (NIDOC) affiliated to Academy of Scientific Research and Technology(ASRT)}, issn = {0302-6701}, eissn = {2357-0369}, doi = {10.21608/ejss.2020.48114.1403}, abstract = {During two successive growing winter seasons (2016/2017and 2017/2018) at the experimental farm of Meet Ghamr, Dakahlia Governorate, Egypt. A field experiment was carried out to maximizing use efficiency of mineral fertilizers (N, P and K) by application of potassium fulvate (KF) and bio-fertilization (Azotobacter chroococcum DSM 2286) on growth, yield and some chemical compositions of wheat plants (Triticum aestivum L.) variety Giza 171. The layout of the experiment was a split- plot design, with the main plots arranged in a randomized complete blocks design, with three replicates. This experiment includes three main treatments and four sub-main treatments. Where the three levels of mineral fertilization “NPK” (60, 80 and 100% of the recommended mineral fertilization) were assigned in the main plots. On the other hand, the application of potassium fulvate (KF) and biofertilization (Azotobacter chroococcum DSM 2286) were assigned in the sub-main plots. After 75 days from sowing, fresh and dry matter yields, chlorophyll (a, b and a+b), carotenoids in leaves, dehydrogenase activity in rhizospheric soil and the N, P, K, Fe, Mn and Zn in shoots of wheat plants were determined. As well as at harvest stage, weight of 1000 grain (g), yields of straw and grains (ton ha.-1), and their content of N, P, K, Fe, Mn and Zn were determined. The obtained results indicated that, the application of KF and Azotobacter chroococcum alone or in a combination resulted in a significant increase in all studied parameters compared to the control. Under 80 % of the recommended mineral fertilization (N, P and K), the dual application of KF + Azotobacter chroococcum showed a significant augmentation in all studied parameters compared to the control under 60, 80 and 100 % of the recommended mineral fertilization.

At each site, ten samples of irrigation water and adjacent (around 50 m) topsoil (0 – 30 cm) were collected and analyzed. Marginal water irrigation caused slight changes in soil properties. The soil chemical quality index was adversely affected through increasing the pH, electrical conductivity, and exchangeable sodium percentage. Available micro-nutrients (Fe, Mn, Zn, and Cu) and P in SEW-irrigated soils were increased. The physical quality index was also increased, but mainly due to inherent soil properties (particle size distribution) rather than irrigation water. Parent materials governed soil total contents of Cr, Co and Ni, while contents of Cd, Cu, Pb, and Zn were closely related to irrigation water. The environmental quality index showed increasing trend in the ADW-irrigated soils, while a decrease in the SEW-irrigated soils. The marginal water irrigation resulted in positive changes in soil quality index exhibiting increases of 14 and 21 % in the ADW- and SEW-irrigated soils over the Nile freshwater-irrigated soils, respectively.
